A catalog of ready-to-use
libraries plus a command-line tool (
alr) to obtain, build, and incorporate
them into your own projects. It aims to fulfill a similar role to Rust’s
cargo or OCaml’s
alr is tailored to userspace, in a similar way to Python’s virtualenv. A
project or workspace will contain all its dependencies.
Some projects require binary packages from the distribution (Debian/Ubuntu’s apt, msys2’s pacman on Windows). In this case the user will be asked to authorize an installation through the distribution package manager.
Properties and dependencies of projects are managed through a TOML file. This file exists locally for working copies of projects, and the Alire community index stores the files corresponding to its projects.
The complete build environment is set up by setting the
environment variable before running
gprbuild, thus freeing the user from
concerns about installation paths. The user simply adds the used projects to
its own project GPR file with their simple name.
Alire requires a recent Ada 2012 compiler. In practice, this currently means
GNAT Community or GNAT FSF 7.2 onward. The
continuous integration checks are run against Debian stable, Ubuntu LTS,
Windows and MacOS.
